作者 郑宏飞 蒙沛南 《新能源》 1997年第4期28-31,共4页
对太阳池溶液浓度与电导的关系做了初步的实验测量和理论说明,并与用光学折射率法和比重计法测得的浓度做了比较。试图找出一种更为简便的太阳池盐浓度分布的测定方法。

The effect of NaCl on soil strength was investigated in this project based on salinity concentrations of 0 g/L, 5 g/L, 20 g/L, and 50 g/L as well as varying water contents of 15%-20%. Laser particle size analyzer was also performed to explain possible effects. From particle size analysis and strength tests, it is hypothesized that the strength of the soil is increased with the addition of certain salinity concentrations until there are reversed effects, which is between 20 g/L and 50 g/L from our study. The increase of strength is suggested to be the affect of a greater variety of particle sizes. Since NaCI plays a role in the particle size distribution, it also plays a role in the strength of soils. The degree of the effect of the water content also differs from concentrations, and could be due to the variation of hydration film thickness on particles, which is affected by the ions introduced from water. 展开更多
